PRIORITY CLAIM AND CROSS-REFERENCE TO RELATED APPLICATION

This is a continuation of U.S. Non-Provisional patent application Ser. No. 12/771,111, filed on Apr. 30, 2010, which claims priority to U.S. Provisional Patent Application No. 61/175,150, filed on May 4, 2009, which are both incorporated herein by reference in their entirety.

BACKGROUND

1. Field of the Disclosure

The present invention relates in general to kitchen equipment and, in particular, to a system, method and apparatus for cutting foods.

2. Description of the Related Art

Some baked goods are prepared as a homogenous entity of food in standard pans or containers such as baking pans and cookie sheets. The food is then typically sliced into smaller portions such as bars, squares or wedges for removal from the container. The task of slicing the food into desirable shapes is commonly performed by using a knife to make numerous cuts that define the sides of the portions. It can be difficult to slice such food into smaller portions with a knife while keeping the cuts uniform, straight and at an adequate depth of cut. There are many prior art cutting tools that use an array of cutting blades to cut food into smaller portions. Although these designs are workable for some applications, improvements in food cutting tools would be desirable.

SUMMARY

Embodiments of a system, method and apparatus for cutting food are disclosed. For example, a food cutting system may comprise a pan having a lower surface adapted to support food and a cutter and having a base and at least two transverse panels that define a grid extending from the base. A lower surface of the base may have a grid-like, rectilinear array of slots in which the upper end of the grid is mounted. The cutter may be sized to complement the pan. The grid has an upper end with edges that are mounted in the base. The grid also has a lower end with cutting edges for slicing food.

The upper end of the cutter may be concave in shape and have a planar lower end. Either the base or the panels may define a perimeter of the cutter. The base is formed from a smooth rigid material for supporting the grid. Surfaces of the base may be coated in a soft pliable material for user comfort, and the grid may be coated with a food safe, non-stick material. The cutting edges may be configured as straight, triangular points or serrated.

In other embodiments, the base has cylindrical handles in a parallel configuration on opposite ends of the cutter. The base may have tubular arcs extending between the handles, and the cutter may have indicia that define a shape of the cutting edges. The pan may comprise a frame and a false bottom that seats on a lip at the bottom of the frame. The pan also may have vertical walls that are complementary in shape to the panels of the grid.

In still other embodiments, both the cutter and the pan have pivotable handles that engage and interlock for leveraging the cutter into the food and pan. Each handle may be mounted on a hinge. Each cutter handle may comprise a bracket that is radially offset from a respective hinge, and each bracket has a radially offset grip relative to the hinge. Each pan handle may comprise a wire frame that is canted and terminates in an offset rectangular loop for engaging the cutter handle.

DETAILED DESCRIPTION

Embodiments of a system, method and apparatus for cutting food are disclosed. For example, as depicted in FIGS. 1-7, a food cutter 31 may comprise a rectangular base 33 and a grid 35 protruding therefrom. The base 33 may be formed from a rigid but smooth material such as plastic (e.g., ABS) for facilitating handling of the grid 35. In some embodiments, surfaces of the base 33 are coated in a softer, more pliable material 37 (FIG. 7), such as silicone, rubber or other elastomeric materials, for comfort of the user. The pliable material 37 may be molded onto the base 33, formed by dipping, or still other manufacturing techniques.

As shown in FIG. 5, the lower surface of the base 33 is provided with a grid-like, rectilinear array of slots 39 in which the grid 35 is mounted. The upper ends or edges 41 of the grid 35 are inserted and installed in the slots 39, and may be permanently secured thereto via mechanical or adhesive means. In other embodiments, the base 33 may be molded directly onto the grid 35. Likewise, the pliable material 37 may be molded onto the base 33, formed by dipping, or still other manufacturing techniques.

Embodiments of the grid 35 comprise an array of thin rigid strips or panels 43 that may be configured in a radial spoke or orthogonal pattern. Some patterns define a plurality of square or rectangular sections, as shown. The lower ends of the panels 43 have sharp edges 45 for cutting food. For example, the edges of the panels may be configured as straight 45 a (FIG. 5), triangular points 45 b (FIG. 6), or serrated 45 c (FIG. 7). In the illustrated embodiment of FIG. 1, the perimeter of the cutter 31 is defined by four of the panels 43 to provide the cutter with a box-like shape beneath the outermost ends of the base 33.

Embodiments of the grid 35 may be manufactured from stainless steel, aluminum or other food safe materials that are rigid, durable and can repeatedly cut foods without readily dulling. The grid 35 may be coated in a food safe, non-stick material that allows the user to place it over food on a container or pan, such as a baking sheet or pan, press down and cut the food in a single action.

Embodiments of the grid comprise two or more food safe, flat metal strips that are approximately 3.5 inches tall by about 12 to 36 inches long. These dimensions vary based on the size of the cookie sheet or baking pan in which the grid is designed to fit. The strips used to form the grid may be manufactured in the form of an integral grid or as independent strips that are joined together to form the grid through mechanical means (e.g., food safe solder, clamps or screws). Again, the entire device, or only the grid, may be coated in a food safe, non-stick material.

The grid also may be formed through the use of a mold in which molten metal is poured and cured. The components work together to form the grid. When joined together, the metal strips form sections of the grid at specified intervals. The metal strips may be cut to desired lengths and attached based on the desired sizes of the food portions.

Some embodiments are well suited for applications such as cookie cutters for “bar” shaped cookies 51, 53 (FIG. 11). These designs allow users to cut bar-shaped cookies in a quick, easy and professional manner. The cutter provides uniformity in size and an enhanced appearance to the cookie bars. Either before or after baking the cookies, the user may place the cutter on the dough in the cookie sheet or baking pan and press the cutter down into it to cut and form the bars.

For example, some embodiments of a cutter employ baking pans having the following dimensions or sizes: 15×10×2, 13×9×2, and 8×8×2 inches. Cutters may be respectively deployed with such baking pans for providing grid patterns having the following exemplary dimensions for the portions of food they cut: 1×3 (e.g., toffee bars, etc.) for the largest pan; 3×4¾ (e.g., lasagna, casserole), 1½×1½ (e.g., petit four) and 1×2½ inches (e.g., larger bar cookies) for the intermediate pan; and 2×2 inches (e.g., brownies, lemon squares, etc.) for the smallest pan. These are only a few examples of suitable applications.

Referring now to FIGS. 8-10 and 12, other embodiments of a food cutting system are shown. For example, FIG. 8 depicts a cutter 61 comprising a base 63 and a grid 65 of panels 66 protruding therefrom. However, embodiments of the base 63 also have large cylindrical handles 67 in a parallel configuration on opposite longitudinal ends of the cutter 61 for improved leverage for the user.

As shown in FIGS. 8 and 10, the tops of the handles 67 may be provided with indicia 68 that define the shapes of the panels 66 and cutting edges 71 of the grid 65 (e.g., corrugated panels 66 a in FIG. 8, and straight panels 66 b in FIG. 10). The bases also may be color-coded for this same purpose. Base 63 may further comprise cylindrical or tubular arcs 69 of an enlarged diameter extending between the handles 67 in a curved configuration to form a more substantial frame for grid 65 for improved leverage for the user. This configuration provides the top of cutter 61 with a concave shape (FIG. 12B) along its longitudinal dimension. The illustrated embodiment of FIG. 12 also has asymmetric spacing (best shown in FIGS. 12A and C) between the panels for forming portions having different sizes with a single cut.

In the illustrated embodiment of FIG. 8, the perimeter of the cutter 61 is defined by the base 63, rather than the panels 66 to provide the cutter with an orthogonal, multi-walled configuration beneath the base 63. The grid 65 may be secured to base 63 as described herein for other embodiments. In the illustrated embodiment, however, grid 65 has a flat or planar bottom at cutting edges 71, and a concave top or upper end for integration into base 63.

The cutters described herein may be used in conjunction with cookie sheets, cake pans or baking pans, such as pan 81 depicted in FIGS. 9 and 10. Pan 81 comprises a frame 83 and a false bottom 85 that seats on a lip 87 on the bottom of frame 83. Pan 81 may be provided with corrugated vertical walls 89 a (FIG. 9) or smooth vertical walls 89 b (FIG. 10) to match the patterns of their respective panels 66 a, 66 b on the grids on the cutters. As shown in FIG. 10, embodiments of cutters 61 have a larger vertical height than the pan 81 has depth, such that base 63 is designed to avoid contact with the food in pan 81 during use.

FIGS. 13-15 depict embodiments of a food cutting system having a cutter 101 comprising a base 103 and a grid 105 of panels 106 protruding therefrom. Cutter 101 is a hybrid of the previous embodiments, in that it has a flat top and bottom, but with enlarged end frames 107 for better support. Both cutter 101 and its pan 108 may be configured as any of the embodiments described herein, with additional features.

For example, both cutter 101 and pan 108 are provided with handles 111, 113, respectively, at each longitudinal end. Handles 111 are pivotally mounted to the upper end of cutter 101 at hinges 115 on end frames 107. Handles 113 are pivotally mounted to the lower ends of pan 108 at hinges 117. Each cutter handle 111 further comprises a bracket 119 that is radially offset from hinge 115. Brackets 119 extend substantially linearly, but terminate in a radially offset grip 121 that protrudes in the same direction relative to hinge 115. Each pan handle 113 comprises a wire frame that is canted at a large obtuse angle near a midpoint 123, and terminates in an offset rectangular loop 125 that extends even further in the same direction as the cant.

In operation (FIG. 15), pan 108 contains food and cutter 101 is aligned and placed in the pan (FIG. 15A), such that the cutting edges 131 of the grid 105 are located in the pan 108 on the top surface of the food. Pan handles 113 extend from the lower longitudinal ends of pan 108 and rest on the underlying surface that supports pan 108. Cutter handles 111 initially rest on top of base 103, but are rotated outward and away from cutter 101 until grips 121 rest on the underlying surface. Cutter handles 111 are narrower in lateral width than pan handles 113, such that they locate within the respective wire frames of pan handles 113.

As shown in FIG. 15B, the pan handles 113 are then lifted slightly until their rectangular loops 125 come to rest on top of the brackets 119 of cutter handles 111. The user then pulls grips 121 outward and upward to rotate cutter handles 111 against the rectangular loops 125. This causes a leverage action by cutter handles 111 as the rectangular loops 125 slide inward along the upper edges of brackets 119. Continued rotation of cutter handles 111 (FIG. 15C) causes the grid 105 to steadily cut into the food in the pan 108 and slice the food in a very controlled and precise manner. The cutter 101 is then removed from the assembly by reversing these steps so that the sliced food may be removed from pan 108.

FIGS. 16 and 17 illustrate embodiments of a food cutting system comprising a pan 151 and a cutter 153. Unlike previous embodiments, cutter 153 does not employ a grid of panels; rather, it only has a single stiff panel 155 (FIG. 17) with a cutting edge 157. Cutter 153 has a base or handle 159 for rigidly supporting the panel 155. Handle 159 may be provided with indicia 161 that depicts the shape of panel 155 and cutting edge 157, as previously described herein for other embodiments.

From handle 159 extends two pivotable and retractable (e.g., telescopic) arms 163. In FIG. 17, arm 163 a is shown in a retracted and pivoted position, while arm 163 b is shown in an extended and aligned position. The pivots 167 between handle 159 and arms 163 are axially aligned with the lateral ends 165 of panel 155. In addition, cutter 153 is provided with alignment grooves 169 that may be located on the ends of arms 163. Grooves 169 are provided for aligning cutter 153 with various reference marks 171 (FIG. 16) located on the upper flange 173 of pan 151.

The devices with the dimensions described elsewhere herein also may be provided for this latter guide and blade embodiment. Such designs also may incorporate a loaf pan application for foods such as banana bread, cranberry bread, etc. A standard loaf pan is 9×5×3 inches, and the cutting guide slots may be positioned at, for example, one-half inch intervals along the sides of the pan.

In still other embodiments, a food cutting system comprises a pan having a lower surface adapted to support food. A cutter is unattached to the pan and has a base and at least two transverse panels that define a grid extending from the base and sized to complement the pan. The grid has an upper end with edges, most or all of which are located in the base. The grid has a lower end with cutting edges adapted to cut food. The upper end may be concave in a longitudinal direction with the lower end flat. The panels may define a perimeter of the cutter, with the panels being orthogonal to each other. Alternatively, the base defines a perimeter of the cutter.

The base is formed from a smooth rigid material. Surfaces of the base may be covered or coated with a soft pliable material, and the grid may be coated with a food safe, non-stick material. A lower surface of the base may have a grid-like, rectilinear array of slots in which the upper end of the grid is mounted. The cutting edges may be configured as straight, triangular points, serrated, etc.

In other embodiments, the base has cylindrical handles in a parallel configuration on opposite longitudinal ends of the cutter. The base may have tubular arcs extending between the cylindrical handles in a curved configuration, and the cutter may have indicia that define a shape of the panels and/or cutting edges. The pan may comprise a frame and a false bottom that seats on a lip on a bottom of the frame, with the false bottom being adapted to support the food on the lower surface of the pan. The pan may have vertical walls that are complementary in shape to the panels of the grid.

In still other embodiments, both the cutter and the pan have handles that are pivotable at each longitudinal end thereof for engaging each other and adapted to provide leverage between the cutter and the pan for forcing the panels into the food. Each handle may be pivotally mounted on a hinge to a respective longitudinal end, with the hinges of the cutter located an upper ends thereof, and the hinges of the pan located on lower ends thereof. Each cutter handle may comprise a bracket that is radially offset from a respective hinge, and each bracket has a radially offset grip relative to the hinge. Each pan handle may comprise a wire frame that is canted at a large obtuse angle near a midpoint thereof, and terminates in an offset rectangular loop that extends even further in a same direction as the cant.

Some embodiments of a food cutting system comprise a pan having a lower surface adapted to support food. A cutter is unattached to the pan and has a base and a panel extending from the base. The panel has an upper end located in the base and a lower end with a cutting edge adapted to cut food. The base comprises a handle and two arms that are pivotable. The arms may be telescopic, such that they are extendable and retractable relative to the handle. The base may have indicia that depicts a shape of the panel and cutting edge. The handle may have pivots for the arms that are axially aligned with lateral ends of the panel. The cutter may have alignment grooves for aligning the cutter with reference marks located on the pan, with the alignment grooves located on lateral ends of the arms.
